Sniffy,

Yeah, just keep a bottle handy for the occasions when you can't get to a decent servo.

51Jay,

Thanks for the details on the location and price, what is your suggested mixing ratio, I've heard between 15-30%.

Giz01,

Couldn't they find a decent car to perform the test on?? Just kidding. I think it is sensible when racing to add it just for added protection.

Ait,

Your the one who has been running your car on 98+booster, notice any difference? Just means that we don't advance out timing as much as we would with 100RON fuels.

Everyone,

I don't like to get covered in any chemicals, whether cancer causing or not, just be sensible and don't sniff or drink it.

See'ya

If the octane rating of Toluene is really 122 then adding

10% gives 100.4

15% gives 101.6

30% gives 105.2

I've decided to keep the tuning for BP 98 octane and add 10%

when racing on full boost as a hedge against detonation

51Jay,

Don't want to burst the buble but at 20% mix the RON improvement is +2.5 and 30% is the maximum recommended, therefore +3.7RON is the best your likely to get. This is taken from an article in a magazine and tested on a knock engine. This is still more than enough to protect you from detonation, therefore it is still worth doing.

Doesn't work like that I'm afraid, life would be so much easier if it did. The fact is you can't work it out. The only way to determine the RON(research octane number) is through the help of a $200,000 knock engine, which all oil companies use for testing of there fuel's RON.

Don't believe all of the bottles claims about there octane boosting ability either, the set there own scales which don't reflect well to real life. If you want guaranteed high octane then use an unleaded race fuel such as Elf or VP Motorsport Fuel 103, about 107RON, the highest you'll ever need to run in any normal car. With the higher octane you can advance timing and get more power also.

51jay,

Toluene is good stuff, if you don't mid premixing it, just remember not to drink the stuff, some of the other guys use it as mouth wash. Go figure!:bahaha:

thats cause we are tough, and have cast iron guts from drinking to much coke

Premium unleaded's like the BP Ultimate, Optimax etc. are supposed to provide better fuel economy due the increased fluid density. I don't know why an octane booster would improve the fuel economy, but if it does that's great. Not likely to offset the cost though at $20 per 60L.

How do you work it out ??   I'm using 98 octane for the BP Ultimate and 122 for the Toluene which are the figures they claim and just multiplying and dividing the appropiate numbers

Roughly,

The BP ultimate 98 stuff would be a closer guestimate due to it having the lowest % content of aromatics.

The mixture of 30% toluene to 70% BP98 will yeild an approximate RON of 105.

Well the tune up + Toluene must have done something. Just back from Willowbank. My previous best 14.8 dropped it to 14.3 good enough to cream 3 x commydoors including a HSV Club Sport 5.0LV8.......Skylines 3...commydoors 0 :)

14.3 @95, 14.6 @ 99.7 ?? 14.8 @ 91

Was very hot, Track temp 42' Iwas leaving after 4 runs at 6.15 pm when a few other Skylines were just arriving. In retrospect I should have stayed on and run acouple more when everything had cooled down a bit.

MRE Still behind you in the mph, just couldn't make the 100.

I'm really looking forward to Wed night though, should be pay off night

GTS-T V Spec :) and especially Club Sports that do huuuuuge burnouts :)

    • Im not entirely sure exactly what or where its leaking from, he started to pull the boots to swap to my new tie rods + ends and it just vomited fluid, so he closed em up up, swapped the rod ends to the old rods and let me know so I can figure a solution out, im guessing its all origional as as I passed 103k miles earlier this year im sure its just in need of a full overhual/rebuild anyways.    If i could just yank it off and be good it wouldn't be an issue to ship it out and wait for the turnaround but the guy I work with doesnt really have space to keep my car for a week or two at a time, would rather drop it off and have a replacement ready to drop in
    • What do you mean by "seals"? Internal hydraulic seals (ie, is it leaking PS fluid?) or the rack boots that close the rack onto the tie-rods? Because the former is a rebuild, and the latter is trivial that you or any nearby mechanic could do. Dunno about the cowl. Just buy what you think is required and get anything else you find/break afterwards. Wing? Dunno. Don't like R33s enough to pay attention to them. Mirror glass is just glass (on the surface that you want to polish). Go for it.
    • Hello! Long time lurker, been using the forums to address concerns and questions from afar for a while but I've struggled to find some answers so I guess its about time I made an account and formally asked some more knowledgeable people, since finding local skyline owners is hard (and shops that are knowledgeable or trustworthy to work on 'rare' cars are non existent out where im at, as skylines are quite uncommon to find in the wild around here). So the main 3 questions I have, 1: Steering rack has blown seals, well.. they kind of hold but they are not sealed properly anymore and as my R33 is my DD, i cant exactly rip the rack out and send it off or attempt to fix myself. As most refurb ones are around $1,100 or more shipped, and I have other things I need to work on around the car, I was seeking clarification on whether an S15 rack will more or less bolt right in, and whether a common mechanic could do any other required work to get it to fit. I ask, as I've found a supplier than can sell a manufactured as oem one for around 400, if not I'll likely order a used one from Jacks JDM, and take a risk on the seals there. The second question i have is that im replacing the front wiper cowl and have planned to buy 4 new clips and a new center clip but wasnt sure if there were any other clips that would also need to get replaced while I was at it. Given im sure any that are there now will simply break when I remove the old cowl... Last thing would be a fairly straight forward question, i think. If I manage (strong if, finding one has proven to be a pain) to find a R33 GTR spoiler/wing will it require much modification to bolt to a S2 R33 GTST? I've read the bolt patterns dont match but otherwise would bolt in, only options I have found with much luck is China stuff on ebay and carbonetics, which has a nice $650 shipping fee... so if anyone has any pointers where a US chap could locate one that would be great Random side question as well, the mirrors as I understand are mirror glass, and as im planning to polish my windows from water spots and surface scratches, i was hopeful cerium oxide would be fine for them too, as my research points to, but clarification is always nice. Any pointers would be appreciated, and while I have scoured the internet for answers if I missed a prior post somewhere that may answer these directly please point me towards it, as i must have simply missed it. I have seen a post here or there that has mentioned it, but I usually get 50-50 answers, or half answers... I dont have a lot of fab experience or mechanic experience, outside of hydraulic and pneumatic stuff I did in the military and with how hard it is to source stuff in the US, id rather not wing it and hemmoraghe money lol. Thanks guys! Sorry for the monumental first post haha
    • Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!
    • Got you mate. Check your email!
